COIN-OPERATED ELECTRIC APPARATUS.

SPECIFICATION forming part of Letters Patent No. 528,911, dated November6, 1894. Application lecl August 30, 1889. RenewedApril 7, 1894. SerialNo; 506,774. (No model.)

To all whom," it may concern:

Be it knownthat l, JOHN H; ELFERING, a citizen of the United States, anda resident of the city of Cincinnati, in the Acounty of Hamilton andState of Ohio, have invented certain new and usefullmprovements in Coin-Operated Electric Apparatus, of which the following is a specification.

The several features of my invention and the various advantagesresulting therefrom, will be apparent from the following description andclaims.

In the accompanying drawings making a part of this specification,-Figure1, Sheet 1, represents a view of the apparatus embodying my invention,as seen after the rear portion of the box inclosing said apparatus isremoved. This figure may be described as a rear elevation of theapparatus proper. Fig. 2, Sheet 2, is a vertical transverse section fromfront to rear,of the apparatus, showing one of the operating handles andits connecting levers, and novel rack and pawl combinations, wherebycertain novel and advantageous results hereinafter specified areattained, Said section being taken at the line e, e', of Fig. 1, thatside of the section which faces toward the left in Fig. 1 being shown.Fig. 3, Sheet 2, is a vertical transverse section of my apparatus,showing the mechanism whereby the coin dropped'into the apparatus,

unlocks the handles and permits them to be raised. This section is takenat the dotted line z, z, of Fig. l, and that side of the section shownis the one which faces toward the left in Fig. 1. Fig. 4, Sheet 2, is atop view of the spring circuit breaker of the limiting device for makingorbreaking the electrical current controlled thereby. Fig. 5, Sheet 2,is a top View of the clock mechanism operating as a part of saidAlimiting device. Fig. 6, Sheet 2, is a rear view of the operating tubeor rack which carries the core-sheath of the coil, and of the lever forengaging a stud on the said rod when the latter reaches a certain'elevation. Fig. 7Sheet 2, is an end elevation of the clockmechanism foroperating vthe tube or rack-which carries the core-sheathof the coil.This elevation is of that end of said mechanism which is at the righthand thereof in Fig. l. InFig. 7 the cord is shown wrapped around thepulley p2, as is necessarily the case before the cord is drawn down, andbefore the pulley p2 has been turned. Fig. 8, Sheet 3, represents inrear elevation, means of employing electric currents in my apparatus,and also means for starting the electric current through my apparatus,and for stopping the further fiow of said current, as hereinafter fullyexplained.

Fig. 10, Sheet 1, is an enlargedelevation of the coil and its connections, and showing by solid anddotted lines, the directions in which the primary .and induced currentsmove. Fig. 11, Sheet 1, is a section taken at the dotted line y, y, ofFig. 1, that face of the section which faces toward the left 4beingshown, the purpose of the section being to illustrate the junction ofthe lever 0.2 of the operating handle, and of the rod designed to closethe electrical circuitand the immediate connections of the said rod.Fig. 12, Sheet 2, is a side elevation of the oscillating pendulum arborand its connections with the balance wheel. Fig. 13 is a side detailView of the device for positively setting free the brake wheel from theaction of the brake, in readiness for allowing the de` vice forincreasing the intensity of the current to be duly set in operation. Fig14 is a vertical central section from front to rear of one of'thehandles, whereby the person desiring to receive the electric shockoperates the apparatus, a portion of the lever to which the handle isconnected being shown in similar section, the figure illustrating thepreferred mode in which electrical connection is made with the handle.

A, A, are the handles to be grasped bythe person who is to receive theelectrical shock or current. Each handle A is rigidly connected to abent lever, having portions a', a2, the lever being pivoted on a bearinga3. (See Fig. 2.) At the inner end of each lever a', a2, is pivoted ata7, a double pawl having the pawls or limbs respectively marked d5 andas, rigidly connected together. A spring rack B has two recesses,respectively marked b and b2, adapted to receive the pawl a6. Thisspring rack is fastened at b3 to lever a2, and accom- IOO panics thelever a2 and pawl a6 in their ascent and descent. This spring rack Bexerts its elastic tendency pressing against the pawl 0.6, and the pointof said pawl will be either in the recess h2 or recess b as shown. Aconvexly curved stationary rack Whose radius is approximately the saineas that of the curve described by the inner end of the portion d2 oflever a', n.2, has recesses c adapted to receive the pawl c5. At thefoot of this rack is a fixed arm c2, located as shown, and adapted toengage the pawl 0.5 as the limb a2 of lever a', a2 descends. Theends ofthe two arms a2 of the levers a', a2, are connected to a rod D, therebysecuring among other objects unison in the ascent and descent of thehandles A. These handles therefore rise together and descend together.

Before passing to a description of the otherI portions of my apparatus,I will describe the mode in which the said handles, pawls and racksoperate in connection.

When the handles are dropped, they hang down as shown in Fig. 2, and theother parts of the mechanism are in the position shown in Fig. 2. As thehandles are raised, the point of the pawl a5, being held in an elevatedposition by reason of pawl a6 being in the depression b2 of the rack,will pass down infront of and Without touching the rack. When thehandles have been raised to a horizontal position, the point of the pawla5 will impinge against the defiecting plate 02, and be turned towardthe portion a2 of the lever a', a2. As the point of said pawl is thusturned, the end of the pawl a is forced out of depression b2 and intob', the elasticity of the rack B causing the depression b to lit overthe point of the pawl a6 and hold it in position. As the handles aredepressed part way, as shown by dotted lines in Fig. 1, the pawl a6 willbe lifted, and will successively engage the successive teeth c of thestationary rack C. By these means the handles cannot be again raised toa horizontal position until they have been dropped to their lowestposition. When thus dropped all the way down, the point of the pawls a5is moved outward from the lever a2 by means of the deecting stud orprojection c3, and the point of the pawl a is consequently changed fromthe recess b to the recess b2 of the rack. At the same time a suitablelook, which forms a part of the apparatus, prevents the handles beingagain raised until a coin of a designated denomination is dropped intothe apparatus. The preferred description of such lock to be employed isas follows, viz:-An inclined bolt L Whose operative end pointsdownwardly and inwardly toward the front wall W of the apparatus, slidesin bearings L', L', secured to a suitable support as L6. A slit orpassage Way L2 is present in the said front Wall of the apparatnsandinclines downward and inward toward the coin holder L3. The coin holderL3 is provided with a vertical slit of a size sucient to receive thecoin. The coin holder is provided with a transverse notch L4. This coinholder is rigidly connected to the respective levers a', CL2, of therespective holders, by means of the bar c4. When the handles are attheir lowest point of depression, the holder L8 is in the position shownin solid lines in Fig. 3. The point of the bolt L then rests against theedge of the coin holder LS as shown in Fig. 3. When no coin is in theholder L3, the eleva tion of the handles will be prevented by the pointof the bolt L entering the notch L4 and engaging the upper or verticalwalls thereof, as the top of the holder is moved toward the bolt by theattempt to elevate the handles. After a coin has been dropped in theholder L3 the coin indicated by L5 fills the center of the notch andpresents a rounded surface to the point of the bolt L. An attempt toraise the handles A will now be successful, for the reason that as theyare elevated and the coin holder turned toward the bolt, the peripheryof the coin acts as a cam and raises the bolt, the point of the latterslipping over the periphery of the coin and at the same time retreatingupward, sliding in its bearings. As the handles continue to be raised,the coin holder descends, and assumes the position shown by dotted linesin Fig. 3, and the coin drops out of the holder and falls into asuitable receptacle L?, in the present instance consisting of a boxattached to the rear side or door M of the apparatus, shown in Fig. 1.When the door M is closed,the box is in position beneath the coinholder. When the handles A are again dropped down, the coin holderslides back under the bolt L, raising the latter by means of the beveledsurface L8 onit and the beveled portion L9 of the lower end of the boltimpinging against one another, and the surface L8 of the holder actingas a wedge or cam by lifting the bolt and at the same time passing byit. Thus the coin holder is returned to place, as shown by solid linesin Flg. 3, in readiness for another coin to be dropped therein, and inthe meantime the coin holder is securely locked as aforesaid and thehandles prevented from descending until the insertion of another coin inthe coin holder. The bolt L is at all times prevented from falling toolow by means of the pin L10 fixed thereto immediately above the upperbearing L.

N indicates a battery of any suitable description, preferably located asshown on the iioor of said box containing my apparatus. From one pole ofthis battery, the wire l runs to the spring armature k2, with whichlatter it connects, being preferably connected to the stationary base ofthe spring armature k2 through a screw connection as k3. A wire 2 isconnected at one end to a lixed stud k, and at the other end to a fixedstud t. Against this stud, presses at all timos, except when removed byhuman agency, the spring 3. To

the rear end of this armature 3 is connected one end of a wire 4, whoseother end is con- IOO erwise termed, an induced current.

therefore depresses this stud 7c.

nected to the coil S. That portion of this wire 4, which extends fromthe post n', (see Fig. l0,} to the coil is shown in dotted lines. Awire5 is at one end connected to the other lpole of battery N, and at itsother end is conthen be in communication with the coil byv way ofarmature post n3, armature h5, post n, and wire 5%. It will be observedthat the connection between said post n3 and the armature 'a5 will beusually established (as shown) by means of the screw fn" of saidarmature, against the end of which screw ng the armature (when not drawnto the coil) presses, the purpose of this screw beingto adjust and keepthe armature nearer to or farther from the coil as desired. The coil Sis constructed in any of the well known methods for use in connectionwith a primary current and a secondary, or as the latter is oth- One ofthe handles A is put into connection with wire 6, one end of said wirebeing fastened to handle o? and the other to the coil S, that portion ofthe wire 6 which extends from post 'p7 to the coil being shown in dottedlines in Fig. 10. The other of the handlesA is put into connection withwire 7, one end of said Wire being fastened to the handle 0.2, and theother end to the coil S. That portion of the wire 7 which extends fromthe post its to the coil S is shown by dotted lines in Fig. l0.

The elevation of the handles A depresses the vertical rod K. This rod Kslides in journals as 7a4, 7.04. This rod is connected to one of thelevers a', a2, of one of the handles at the point 165, by a pivotalconnection. The upper end of the rod is elastic, and this accommodatesitself to the curve described by the pivot 105. Farther down on the rodK, a stud k is fixed to it. Depression of the rod The latter in itsdescent strikes against the free end of spring armature k2, and forcesthe latter against the stud 7a4. In this way, an electrical circuit isimmediately formed, the circuit extending through conductors l, 2, 3, Ltand coil S, and thence through the coil by wire 5% through the armatureand its posts to wire 5, and thence by the latter to the battery. Thiscircuit magnetizes the cores of the coil S,

which latter then attract the free end of armature fr, and said free endmoves forward and into contact with them. When the free end of thearmature is in contact with the cores of the coil, the armature has leftthe post ne, and being out of contact with said post ne, theV primarycircuit is broken. An induced current passes through wire 6, to theadjacent handle A, thence through the operator grasping the handles,thence through the other handle A, and thence through wire 7, to thecoil. In this way, the raising of the handles communicates an electricalshock to the person holding them. When the primary circuit is broken,the core is demagnetized, and the armature is permitted to again springback to the screw rtg of the post TLG. The induced current which passesthrough the partial circuit formed by the wires 6, 7, and handles A, asheretofore mentioned, and the person holding the handles and completingthe circuit, is induced as frequently as the armature n interrupts theprimary current.

The apparatus is provided with means for automatically causing theintensity of the electric current to be increased or-diminished afterthe circuit through the operator has been formed. The preferred form ofthis mechanism is4 as follows, viz: To the rod of( connecting thehandles, is connected one end of a spiral spring P. The bar at the pointwhere the spring is thus connected, is preferably formed into acrank asshown, or eye to prevent the cord from slippingr along the bar, ineither direction from its proper place. The other end of this spring isconnected to the lower end of a cord p', which latter passes up and overand around a pulley p2, and the upper end of the cord is fastened to theperiphery of this pulley. This pulley p2 turns loosely on its shaft p27.At the side of the pulley p2 and concentric with the latter, is a pinionp4 xed to the sleeve p3 turning on shaft p27. A pawl p5 pivoted to theloose pulley p2 engages the pinion p4, when the pulley p2 is turned(when 'looking at Fig. l) from the right over to the left, that end ofthe cord p', which is attached to the spring P, being subjected to adownward draft by the elevation of the handles and the depression of therod a7. A toothed wheel p6 is fixed on the pulley 102. Al rack S2 slidesvertically, its reciprocating movement being kept in a vertical line bymeans of a suitable' guide, which latter, in the present instance,consists of a vertical rod S3 fixed at each end to the frame of theapparatus and passing through the rack S2. The rack S2 thus slides uponthe rod S3, the reciprocal movement of the rack S2 being limited bymeans of stops S4, S4. The rack S2 is provided at or near its upper endwith an arm S', and the latter extends over a portion of the adjacentend of the core and is connected to the sheath S5, surrounding the coreof the coil S. Teeth of the rack S2 engage the teeth of the wheel p6. Inconnection with the wheel p is a train of wheels and an escapement forregulating the rotation of the wheelp, rotated by pulley p2. Onedescription of such train is shown and consists of gear wheel p7 fixedon sleeve p3 turning on shaft p27, pinion p8 fixed-on shaft p9, whichlast named shaft also carries the escape-wheel p10. The escapementpawlp11 is fixed to and suspended from the shaft or pivot p18. The shaftp12 carries a' balance wheel p16, which latter pref- IOO IIO

IZO

erably carries on its periphery a half tooth or stud p19, for the bettermaking frictional contact with the brake rod pls. Adjacent to the wheelp16 is the balance coiled spring p17, connected and operating in amannner common to clock Work. The pawl p11 of the escapement beyond thepointp where it is pivoted, is provided with an extension rigid with it.The end of this extension is provided with a fork p15, between theprongs of which is a pin p14, rigidly fixed in the balance. Thus theoscillation of the escapement pawl p11 in one direction, turns thebalance wheel p16 against the spring p17, and this spring operates tooscillate the pawl in the opposite direction.

As the operation of the escapement pawl and its wheel p10 is wellknown,further mention thereof is herefrom omitted.

The brake rod p18 is pivoted at one end p23 to the clockwork frame Q.(See Fig. l.) The middle portion of the brake rod rests upon theperiphery of the wheel p16. Upon the opposite, viz: the free end of thebrake rod rests one end of the lever p20, pivoted at 21 tothe frame ofthe apparatus. The other end of this lever 1920 projects across the rackS2, and close thereto, and is subject to impingement by the stud p22 ofthe rack S2 as the latter rises. The manner in which this portion of myapparatus operates is as follows, viz:

As the operator lifts the handles A, A, the rod CLT of levers a', a2, isdepressed, and pulls the spring P and stretches it. Vhen the handleshave been raised, the circuit aforementioned is closed, and the operatorreceives theinduced currentas aforementioned. The spring P, beingstrained, pulls upon cord p and rotates the pulley 212 and wheel p6. Therotation of this is rendered slow and uniform by means of the clock worktrain of wheel, escapement, balance wheel and spring aforementioned. Thewheel p6, by its rotation, moves the rack SL upward thereby continuallyincreasing the intensity of the current, passing through the operatoruntil the stud p22 on the rack S2 strikes and elevates the adjacent endof the lever p20. The other end of the latter then presses down thebrake rod p18 upon the wheel p16, and thereby stops all rotation of thelatter, the stud pl aiding in preventing the wheel p16 from slippingunder the brake. Thus further elevation of the rack S2 is prevented, andthe maximum degree of intensity of the electric current to which theoperator is subjected, is reached. Vthen the rod al is elevated to theposition shown in Fig. 2, all upward strain on rack S2 will have ceased,and the rack S2 will then descend to the lowest point of its movement,and reassume the position shown in Fig. l. lVhen the handles aredropped, the tension on spring P being gone, the weight of the rack S2and the connections rigidly attached to it, causes it to descend. As itdescends, it turns the pulley p2 and winds the cord p thereon. Thepulley being loose on the shaft p3, and the pawl p5 sliding over thepinion p", does not, during the operation of rewinding the cord, turnthe clock Work, and is not retarded by said clock work. The frontend ofthe shaft p3 carries at the outside of the front Wall of the machine, anindex lingerpQQ, which indicates on a dial on the outside of the saidwall, the intensity of the current to which the operator is subjected.The finger and dial being at the front of the machine, are in full viewof the operator.

The pressure of the brake p18 on the brake wheel p16, is preferablyalways positively relieved at the time the apparatus is put intoposition for giving a fresh electrical shock. The rear end of the brakebeyond the point p23 where the latter is pivoted to the frame, isprovided with an arm p27. To the free end of this arm is attached theupper end of a rod or cord p28, whose lower end is connected to theouter end of the spring arm p29, the inner end of this spring arm beingproperly connected to the frame of the apparatus. Vhen the handles A areelevated by the operator, the free ends of levers ct', a?, and the roda7 are depressed. The rod a7 strikes the arm p2, and thereby draws downthe rod 1928,

and the arm p27 of the brake p28. Thus the brake is lifted sufficientlyto be out of contact with the brake wheel, and the mechanism forincreasing the intensity of the electric current is immediately free tooperate.

I will now describe certain novel means for limiting the duration of theelectric current.

To the bar al connecting the levers a', a2, of the handles A isconnected (see Fig. l) the lower end of a spiral spring E, and the upperend of this spring is connected to one end of a cord e', which latterextends up and around a loose pulley e2, and fastened thereto at onepoint and down the other side thereof, and thence extends down and itsother end is there connected to the weight c, sliding vertically in theguideways e7, e?, connected to the frame of the apparatus. The loosepulley c2 turns loosely on shaft c3, carrying pinion e5 fixed thereto. Apawl e4 pivoted to the pulley e2, engages with pinion e5. A suitabletrain of clock work, doc., regulates the rapidity and uniformity of therotation of pulley e2, when turning in the direction in which the pawle4 engages the pinion e5. Such a train consists as followsz-Rigidlyfixed to shaft e3 is gear wheel e8, which latter meshes with pinion e9,fixed on shaft cm. To this latter shaft is also fixed gear wheel emeshing with pinion cl2 on shaft cl3, which latter also carriesescape-wheel e, fixed to said last named shaft. On a pivot shaft cwoscillates the escapement pawl ew. An extension of said pawl located onthe other side of said shaft e16 from where the pawl proper is located,is provided with a fork whose prongs have between them a pin e fixed inthe side of the balance wheel ela, the latter being fixed on pivot shafte2", and connected to a balance spring ew, combined and operating in theman- IOO IIO

draws with it the weight e6.

membered that the elevation of the handles ner well known to all clockWork. The manner in which this portion of my apparatus operates is asfollows:

The handles being elevated and the rod a7 depressed, the spring E isstretched. The latter draws elastically upon the cord e and rotates thepulley e2 as fast as the clock work will permit. As the cord on one sideof the pulley is drawn down by the spring E, it is drawn up on the otherside of the pulley and It will be reclosed the circuit, and started theinduced current through the operator. After a given time, the top ofweight e6 will have risen to the bottom of spring circuit breaker 3. Thecord c passes freely through a small opening in the end of this armature3; but this opening is too small to allow the weight e5 to pass throughit. Consequently as the weight e5 rises and strikes the bottom of thearmature, it lifts the spring circuit breaker 3 off of the connectingstud t,and breaks the electrical circuit. The circuit now no longervpasses through the apparatus, nor through the operator. For the latterto obtain a new electrical shock, he must drop the handles, whereupontheywill be locked. He must then drop in a second coin in order tounlock the handles, so that he can raise them. When the handles areraised, the strain on the spring E is withdrawn and the weight falls,the pulley rotating with it and its pinion c5 raising the pawl andslipping beneath it, the clock work standing still. The stud z" abovethe spring circuit breaker, 3, performs the office of a detent andprevents the weight e5 as it lifts' the spring circuit breaker, 3, fromlifting the latter too high. y

By the mechanism heretofore described, the operator in order to preventthe intensity of the electrical'circuit increasing, has been obliged tocut it off altogether by dropping the handles, as shown in Fig. 2.

I will now describe a means whereby the operator, while experiencing theelectrical current, can, at will, prevent the current from .increasingwithout breaking the electrical circuit, and can therefore enjoy anygiven degree of intensity of electrical force indicated on the dialduring the entire time allotted by the mechanism, of which spring E,weight'e6 and spring circuit breaker 3 are elements. These means areillustrated in Figs. 8 and 9.

It may be here remarked, that the use of the means aforesaid is not tobe confined to the modification of electrical circuits shown in Fig. 8,but is to be usedin connection with those circuits employed in Fig. l,or any other suitable circuits employed in the apparatus.

The mechanism shown in Fig. 9, and in elevation in Fig. 8, is in thelatter gure shown in connection with said modification of electricalcurrents for the sake of compactness. It may be here premised that whenthis mechanism shown in Fig. 9 is to be einployed the mechanismconsisting of rod K,

stud k', guideways 104, h4, armature 7a2, part los, and stud 7a4 will bedispensed with and the mechanism of Fig. 9, will take their place. Tothe frame of the apparatus is attached an upper bracket V10 and a lowerbracket V5. In the upper bracket V10 is journaled one end of an arm V4,whose outer end is pivoted at V13 to the upper end of a vertical rod V5,the lower end of 'the latter being pivoted at V14 to one end of an armV2, pivoted at V9 to the lower bracket V5. The other end of the arm V2extends beyond the pivot V2 and toward the wall W of the apparatus. Thisfree end of the arm V2 is continually engaged by a Spring arm rack V5,suitably attached, prefverably as shown, to the bracket V5, and having asingle tooth on the lower side of which is the depression V8 of thisrack.` On the upper side of the said tooth is the depression V7. Thespring rack V5 continually presses outward against said free end of saidarm V2. This arm V2 carries the curved downwardly projectingcircuit-closer V so located, as shown, in relation to the stationaryconductor V, as that when the arm V2 descends, the circuit closer V willdescendv and come into contact with the conductor V and close thecircuit. To the con ductorV is connected the wire .1, which latterthereby connects one pole of the battery to the said conductor. To thebracket V10 is connected the lower end of the conducting wire 2 whoseupper end is connected to stud t, as aforementioned. The cross-rod a7 oflevers ft2, a2, passes between the arms V4 and V2. The mode in whichthis portion of my apparatus operates is as follows:

When the handlesA are down as shown in Fig. 2, the position of themechanism will be that shown in solid lines in Fig. 9, the rod a7 havinglifted the parts to that position, the free end of the arm V2 being inthe notch V8 of the rack V5, and the circuit closer V being elevated andout of contact with the conductor V. As the handles A are lifted, therod a2 gradually descends. The arms V4, rod V3, arm V2, and circuitcloser Vremain stationary'and do not descend with the rod a2, being heldin position by thespring rack V6 which notch V8 and the free end of armV2 continue interlocked, until as the handles A are continued to beelevated, the rod a7 in its downward descent strikes against the upperside of armV2, forcing the free end of said arm ont of the notch V5, anddepresses the arms V4, V2, rod V3 and circuit closer V to the positionshown by dotted lines in Fig. 9,the circuit closer resting against andin electrical contact with conductor V. This circuit closer togetherwith arms V2, V4, and rod V5, continues to maintain this position, beingheld therein by the spring rack pressing against the free end of the armV2, and pressing said free end upward. The electrical circuit is fromthe battery and wire 1 through the meehanism shown in Fig. 9, viz:lconductorV,ci1-cuit closer V arm V2, rod V2, arm V4, and bracket ICOIIO

V10, and thence by way of wire 2, to the coil and thence to the battery,the induced current being carried through the operator, allsubstantially as heretofore already shown and described in connectionwith Fig. l.

It is evident that for the arm in its upward movement to impinge againstthe arm V4, and elevate it and thus break the circuit, it, the said arm,must travel much the larger portion of the arc through which it travelswhen the handles are depressed. This construction of the parts therebyenables the operator, after elevating the handles and closing thecircuit, to at any time once partially depress the handles and elevaterod a7 sufficiently to remove the tension from the spring arm p29 andthus allow the brake p18 to act on the brake wheel. The instant theoperator does this, the rack S2 will cease to rise and all furtherincrease of intensity in the current will be stopped. The rack S2 couldbe again started in its ascent, by a second partial elevation of thehandles and a corresponding depression of the rod a7 and a consequentrenewed release of brake-wheel, without breaking the circuit, that is,disturbinglr the position of the parts of Fig. 9, as shown in dottedlines therein, were it not for the fact that the pawl a5, after thefirst complete elevation of the handles necessary to close the circuithas assumed the position shown in dotted lines in Fig. 2, therebypermitting the handles to be dropped as far as desired, but preventingtheir elevation again, and consequent further depression of the rod aluntil the handles A, A, have been entirely dropped and the rod alelevated to its highest point of movement as shown in Fig. 2, and asheretofore fully specified. Thus it will be observed that the operatoris thereby enabled to check the increasing intensity of the electricalcurrent and at the same time enjoy the electric current at any of thegiven rates of intensity indicated on the dial, until the mechanism inwhich spring E and weight e6 and spring circuit breaker 3 play a part,or mechanism the equivalent thereof, after a given time, break thecircuit, and cut olf the electrical current from the operator until thehandles are dropped and the apparatus unlocked by the insertion ofanother coin.

I will now proceed to describe a modification of the electrical circuit,which modification although not as desirable as the system of circuitsshown in Fig. I and heretofore described, I may yet wish at times toemploy. This modification consists in attaching the wire 6 to the posta6of the armature, and the wire 7 to the post n. In this way, a primary orgalvanic current is transmitted to the person holding the handles. If Iemploy this modification, I do not use the secondary wire on the coil,and said secondary coil may be omitted. In such event, the coil wrappedwith a single wire, in connection with the core and circuit breaker asdescribed, transmits an intermittent primary current, theintensity ofwhich is regulated by the sheath as in the induction coil.

While the various features of my invention are preferably employedtogether, one or more of said features may be employed without theremainder, and in so far as applicable, one or more of said features maybe employed in connection with apparatus for similar pur poses, but ofconstruction differing in many respects from that hereinbeforespecilied.

That I claim as new and of my invention, and desire to secure by LettersPatent, is-

l.
